ABSTRACT

A method performed by a head-mounted device can include, based on a front-facing camera included in the head-mounted device capturing an image of a wearable device, configuring the head-mounted device to receive input via the wearable device, determining that a gesture received by the wearable device includes a request to launch an application, and, in response to determining that the gesture includes the request to launch the application, launching the application.

TECHNICAL FIELD

This description relates to head-mounted devices.

BACKGROUND

Head-mounted devices can create a virtual reality or augmented reality environment. Head-mounted devices can capture input via one or more cameras and present an output via a display.

SUMMARY

According to an example, a method performed by a head-mounted device can include, based on a front-facing camera included in the head-mounted device capturing an image of a wearable device, configuring the head-mounted device to receive input via the wearable device, determining that a gesture received by the wearable device includes a request to launch an application, and, in response to determining that the gesture includes the request to launch the application, launching the application.

According to an example, a non-transitory computer-readable storage medium can include instructions stored thereon. The instructions, when executed by at least one processor, can be configured to cause a head-mounted device to, based on a front-facing camera included in the head-mounted device capturing an image of a wearable device, configure the head-mounted device to receive input via the wearable device, interpret, based on gesture data received from the wearable device and a state of the head-mounted device, a gesture, the gesture being included in a library associated with the state of the head-mounted device, and, in response to interpreting the gesture, perform an action associated with the gesture.

According to an example, a head-mounted device can include a frame configured to mount onto a head of a user, a display supported by the frame, the display being configured to face at least one eye of the user, a front-facing camera supported by the frame, the front-facing camera being configured to capture images from a direction opposite from the user, a gaze-tracking camera supported by the frame, the gaze-tracking camera being configured to capture a direction to which at least one eye of the user is looking, and a processor supported by the frame. The processor can be configured to transition the head-mounted device into a state in which the head-mounted device receives input via a wearable device based on determining that the front-facing camera captured an image of the wearable device, and determining, based on image data captured by the gaze-tracking camera, that the user is focusing on an image presented by the display.

The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION

A head-mounted device can receive input via a wearable device, allowing a user to control the head-mounted device with gestures into the wearable device. The head-mounted device can receive input via, for example, a touchscreen display included in the wearable device. The head-mounted device can determine whether a user intends to provide input to the head-mounted device or the wearable device based on camera input received by the head-mounted device. For example, the head-mounted device can determine that the user intends to provide input to the head-mounted device via the wearable device based on a front-facing camera included in the head-mounted device capturing an image of the wearable device. In some examples, the head-mounted device can determine that the user intends to provide input to the head-mounted device via the wearable device based on determining that the front-facing camera captured an image of the wearable device while the wearable device was disposed on an arm of the user. In some examples, the head-mounted device can determine that the user intended to provide input to the head-mounted device via the wearable device based on determining that the front-facing camera captured the image of the wearable device and a gaze-tracking camera captured an image of the user not looking at the wearable device and/or looking at an item included in a display of the head-mounted device.

The head-mounted device can perform actions based on the input into the wearable device. In some examples, the input into the wearable device can include a gesture into the touchscreen of the wearable device. In some examples, the head-mounted device and/or wearable device can interpret the gesture based on a state of the head-mounted device. The state of the head-mounted device can include, for example, a home screen, in which the gesture would be interpreted as selecting and/or identifying an application for the head-mounted device to launch. In some examples the state can include an open application, and the gesture could include an input to the open application such as a swipe gesture, which would prompt the head-mounted device to change a portion of a document displayed on the display to the user.

FIG. 1A is a diagram showing a head-mounted device 100 and a wearable device 150. The head-mounted device 100 can include a frame 102 that supports a display 108, a front-facing camera 110, and a gaze-tracking camera 114. The frame 102 can include one or more rims 104 that support the display 108. In some examples, the frame 102 can include a single rim 104, and present a single display 108 to the user. In some examples, the frame 102 can include two rims 104, which each support a separate display 108, in a similar manner to glasses. The frame 102 can be attached to, and/or include, two temple arms 106A, 106B, which are flexibly attached to a front portion of the frame 102, and rest on a user's ears to support the head-mounted device 100.

The front-facing camera 110 can face, and/or capture images from, a front of the head-mounted device 100, and/or away from a user wearing the head-mounted device 100. While FIG. 1A shows a triangular field of view 112 in two dimensions, the field of view 112 can be conical in three dimensions. The field of view 112 captured by the front-facing camera 110 can be presented to the user via the display 108. In the example shown in FIG. 1A, the display 108 superimposes a menu including the options ‘C’, which can represent a calendar application, ‘U’, which can represent a ride service application, and ‘W’, which can represent a word processing application. This presentation of a menu of applications can be an example of a home screen. The gaze-tracking camera 114 can capture images of the user's eyes, and determine a direction that the users eyes are pointing to and/or objects that the user is focusing on. The objects that the user is focusing on could include physical objects in front of the head-mounted device 100, and/or graphical objects presented by the display 108.

The head-mounted device 100, as described and illustrated below, may include any hardware that may be worn on a head of a user and that leverages or utilizes its position on the user's head, and/or that relies on or augments user abilities (e.g., sight, hearing, or head position/orientation) to provide functionality to the user. In some implementations, functionality of the head-mounted device 100 may alternatively or additionally be provided using other, different types of wearable devices, such as watches, rings, or clothing. For example, the head-mounted device 100 may include or represent glasses, augmented reality glasses, goggles, a hat, helmet, headband, or other headwear, including conventional headwear retrofitted with suitable hardware/software.

In the example shown in FIG. 1A, the wearable device 150 is captured by the front-facing camera 110 within the field of view 112 captured by the front-facing camera 110. The wearable device 150 can include, for example, a smartwatch disposed on an arm 160 of the user. The arm 160 of the user can include an extremity extending from the torso of the user, such as the upper arm, forearm, wrist, thumb, and/or any fingers. The wearable device 150 can include a display 152 attached to the user's arm 160 by a band 154. The display of 152 can include a touchscreen display, which presents graphical output to the user and receives touch input from the user. A smartwatch is one example of the wearable device 150, and the wearable device 150 could also include a ring or other electronic device worn on a body of a user.

FIG. 1B is a diagram showing the head-mounted device 100 worn on a head 170 of a user. The head-mounted device 100 can be supported by the user's ears 172 (only one of which is shown in FIG. 1B) and the nose 173 of the user. When worn on the head 170 of the user, the front-facing camera 110 can face and/or capture images away from, and/or on an opposite side of the head-mounted device 100 from, the user. When the head-mounted device 100 is worn on the head 170 of the user, the display 108 can face toward the user's eyes 174. When the head-mounted device 100 is worn by the user, the gaze-tracking camera 114 can face toward, and/or capture images of, the user's eyes 174.

FIG. 2 is a flowchart showing actions performed by the head-mounted device 100. The head-mounted device 100 can present output 202. The head-mounted device 100 can present the output 202 via the display 108. The output 202 can include, for example, a menu presenting applications that the user can launch, or an application presenting output to the user and ready to receive input from the user.

The head-mounted device 100 can determine the intent of the user (204). The head-mounted device 100 can, for example, determine whether the user intends to provide input to the wearable device 150 (not shown in FIG. 2 ), or to provide input to the head-mounted device 100 via the wearable device 150. In some examples, the head-mounted device 100 can determine that the user intends to provide input to the head-mounted device 100 via the wearable device 150 based on the front-facing camera 110 capturing an image of the wearable device 150, based on the front-facing camera 110 capturing an image of the wearable device 150 being disposed on the arm 160 of the user, based on the gaze-tracking camera 114 capturing images indicating that the user is not looking at and/or focusing on the wearable device 150, and/or the gaze-tracking camera 114 capturing images indicating that the user is focusing on an image presented by the display 108.

If the head-mounted device 100 determines that the user does not intend to provide input to the head-mounted device (206), then the head-mounted device 100 continues presenting output (202). The wearable device 150 can then process any input independently of the head-mounted device 100.

If the head-mounted device 100 determines that the user does intend to provide input to the head-mounted device 100 via the wearable device 150, then the head-mounted device 100 can determine a state of the head-mounted device 100 (208). The state can include, for example, a home state in which the display 108 presents a menu with applications for the user to open, or a particular application that is open. The head-mounted device 100 can take the state of the head-mounted device 100 into account when interpreting a gesture received by the wearable device 150.

In some examples, when the head-mounted device 100 is in the home and/or menu state, the head-mounted device 100 does not send image data to the wearable device 150 in response to the configuration of the head-mounted device 100 to receive input via the wearable device 150. While in the home and/or menu state and ready to receive input via the wearable device 150, the head-mounted device 100 can present the menu via the display 108 instead of via the wearable device 150.

The head-mounted device 100 can interpret the gesture (210) received by the wearable device 150. In some examples, the wearable device 150 can interpret the gesture received by the wearable device 150 via the display 152 and send, to the head-mounted device 100, a signal indicating the gesture received by the wearable device 150. In some examples, the wearable device 150 can send, to the head-mounted device 100, raw touch input data received by wearable device 150 via the display 152. The raw touch input data can include, for example, locations of times of contact of a body part of a user, such as a finger, on the display 152 of the wearable device 150.

In some examples, the head-mounted device 100 can compare the received touch input data to gestures in a library associated with the state of the head-mounted device 100. For example, when the state of the head-mounted device 100 is a home state in which the head-mounted device 100 presents a menu of applications to the user, the library of gestures can include multiple letters, such as the twenty-six letters in the alphabet, with each of the letters being associated with an application that the head-mounted device 100 can launch. In some examples, when the state of the head-mounted device 100 is that an application is open, the head-mounted device 100 can compare the touch input data to swipe gestures that change what portion of a document the head-mounted device 100 displays to the user via the display 108, and/or other gestures associated with inputs to the open application.

After interpreting the gesture (210), the head-mounted device 100 can perform the action (212) associated with the interpreted gesture. The head-mounted device 100 can, for example, launch an application associated with the interpreted gesture, or change presentation of a document based on a swipe gesture.

After performing the action (212), the head-mounted device 100 can determine whether to change a state (214) of the head-mounted device 100. The head-mounted device 100 can determine whether to change the state (214) based on whether an application is launched and/or closed. If no application is launched and/or closed by the performed action, then the head-mounted device 100 can determine that the state should not be changed, and continue presenting output (202). If the head-mounted device 100 determines that the state should be changed, then the head-mounted device 100 can change the state (216) of the head-mounted device 100. The head-mounted device 100 can change the state (216) by, for example, noting that an application is open or closed, or noting that the head-mounted device 100 is in the menu or home state. After changing the state (216), the head-mounted device 100 can continue presenting output (202).

FIG. 3 is a timing diagram showing actions performed by the head-mounted device 100, the wearable device 150, and a user 300. The user 300 can be the person to whom the arm 160 shown in FIG. 1A and the head 170 shown in FIG. 1B are attached.

The head-mounted device 100 can present output 202. The output (202) can include, for example, a menu of applications to open, or an open application.

The head-mounted device 100 can receive gaze data 302 from the wearable device 150 worn by the user 300. In some examples, the front-facing camera 110 of the head-mounted device 100 can capture an image of the wearable device 150 and/or arm 160 of the user 300, as shown in FIG. 1A. In some examples, the gaze-tracking camera 114 can capture images of the user's 300 eyes 174, and/or a direction in which the eye 174 is pointing.

Based on the gaze data 302, the head-mounted device 100 can determine the intent (204) of the user 300. The head-mounted device 100 can determine, for example, whether the user 300 intends to provide input into the wearable device 150, or if the user 300 intends to provide input to the head-mounted device 100 via the wearable device 150. The head-mounted device 100 can determine that the user 300 intends to provide input to the head-mounted device 100 via wearable device 150 based, for example, on the front-facing camera 110 capturing, and/or the head-mounted device 100 recognizing, an image of the wearable device 150 and/or an image of the wearable device 150 disposed on the arm 160 of the user 300. The head-mounted device 100 can determine that the user 300 intends to provide input to the head-mounted device 100 based, for example, on data captured by the gaze-tracking camera 114 indicating that the user 300 is not looking at the wearable device 150, and/or is looking at an object presented by the display 108.

The user 300 can provide touch input 304 to the wearable device 150. The user 300 can provide touch input 304 to the wearable device 150 by, for example, tapping and/or sliding a part of the user's 300 body, such as the user's 300 finger, on the touch screen display 152 of the wearable device 150.

The wearable device 150 can send gesture data 306 to the head-mounted device 100. In some examples, the wearable device 150 can interpret a touch input 304, and the gesture data 306 can identify a gesture interpreted by the wearable device 150. In some examples, the wearable device 150 can send the raw touch data to the head-mounted device 100, and the gesture data 306 can include the raw touch input data, such as locations and/or times of touch input received by the wearable device 150 into the touch screen display 152.

After receiving the gesture data 306, the head-mounted device 100 can determine the state (208) of the head-mounted device 100. After determining the state (208), the head-mounted device 100 can perform an action (212). The action can include, for example, launching an application identified by the touch input or providing input within an open application.

FIG. 4 is a block diagram of the head-mounted device 100. The head-mounted device 100 can include an intent determiner 402. The intent determiner 402 can determine whether a user 300 intends to provide input to the wearable device 150, or to the head-mounted device 100 via the wearable device 150. The head-mounted device 100 can configure the head-mounted device 100 to receive input from the wearable device 150 in response to determining that the user intends to provide input to the head-mounted device 100 via the wearable device 150.

The intent determiner 402 can include an image recognizer 404. The image recognizer 404 can recognize images captured by the front-facing camera 110. The image recognizer 404 can recognize, for example, the wearable device 150, and whether the wearable device 150 is disposed on the user's 300 arm 160 within the field of view 112. The intent determiner our 402 can determine, based on the image recognizer 404 recognizing the wearable device 150, and/or the wearable device 150 disposed on the user's 300 arm 160 within the field of view 112, that the user intends to provide input to the head-mounted device 100 via the wearable device 150. Based on determining that the user intends to provide input to the head-mounted device 100 via the wearable device 150, the intent determiner 402 can transition the head-mounted device 100 into a state in which the head-mounted device 100 receives input via the wearable device 150.

The intent determiner 402 can include a direction determiner 406. A direction determiner 406 can determine a direction that the user's 300 eyes 174 are facing and/or pointing, and/or an object that the eyes 174 are focusing on. The direction determiner 406 can determine the direction and/or focus based on image data captured by the gaze-tracking camera 114. The intent determiner 402 can determine that the user 300 intends to provide input to the head-mounted device 100 via the wearable device 150 based on the direction determiner 406 determining that the user 300 is not looking at the wearable device 150, and/or that the user is looking at an object on the display 108.

In some examples, the intent determiner 402 can determine the intent of the user to provide input to the head-mounted device 100 via the display 152 of the wearable device 150 based on movement of the wearable device 150. An accelerometer included in the wearable device 150 can determine that the wearable device 150 is moving, and the wearable device 150 can send movement data to the head-mounted device 100. The head-mounted device 100 can determine that the user 300 moved the wearable device 150 toward the head 170 of the user 300. Based on determining that the user 300 moved the wearable device 150 toward the head 170 of the user 300, the intent determiner 402 can determine that the user intends to provide input to the head-mounted device 100 via the display 152 of the wearable device 150.

In some examples, the intent determiner 402 can determine the intent of the user 300 to provide input to the head-mounted device 100 via the display 152 of the wearable device 150 based on input by the user 300 to the wearable device 150. The input can be input that is not typically an input to the wearable device 150, and/or is orthogonal to known and/or typical inputs to the wearable device 150. The input indicating intent of the user to provide input to the head-mounted device 100 via the display 152 of the wearable device 150 can include, for example, the user 300 tapping on a side of the wearable device 150 a specified number of times, such as two taps on a side (or other predetermined portion) of the wearable device 150, or a “pinching” gesture on the display 152 of the wearable device 150.

The head-mounted device 100 can include a state determiner 408. The state determiner 408 can determine a state of the head-mounted device 100, such as whether the head-mounted device 100 is in a home state and/or menu state, or whether the head-mounted device 100 is executing a launched application. The state of the head-mounted device 100 can be relevant to interpreting a gesture received by the head-mounted device 100 via the wearable device 150.

The head-mounted device 100 can include a gesture interpreter 410. The gesture interpreter 410 can interpret gestures, and/or raw touch input data received by the head-mounted device 100 from the wearable device 150, to determine a command inputted by the user 300. The gesture interpreter 410 can interpret the raw touch data based on the state of the head-mounted device 100 determined by the state determiner 408. When the head-mounted device 100 is in the home and/or menu state, the gesture interpreter 410 can identify an application associated with the interpreted gesture, and/or interpret the gesture as an instruction and/or request to launch an application identified by the interpreted gesture. The gesture received by the display 152 of the wearable device 150 can thereby be considered to have identified the application to launch.

In some examples, the gesture interpreter 410 can present the interpreted gesture on the display 108 of the head-mounted device 100. The gesture presented on the display 108 by the gesture interpreter 410 may not be a one-to-one mapping of the raw touch data representing the gesture received by the display 152 of the wearable device 150. The gesture interpreter 410 can, for example, map the raw touch data to a letter, and present the letter, in a predetermined form (such as a particular font), on the display 108. The pattern of the gesture that the gesture interpreter 410 presents on the display 108 can therefore be different than the pattern of the gesture received by the display 152 of the wearable device 150.

The head-mounted device 100 can include an application launcher 412. The application launcher 412 can launch an identified application, such as a calendar application, a ride service application, or a word processing application, based on the gesture interpreted by the gesture interpreter 410. The application launcher 412 can launch the application based on the identification of the application by the gesture interpreter 410.

The head-mounted device 100 can include an output generator 414. The output generator 414 can generate output, such as graphical output, for presentation and/or display by the display 108. The output can include, for example, a menu when the head-mounted device 100 is in the home or menu mode, or data included in, and/or information associated with the document when an application is open.

The head-mounted device 100 can include at least one processor 416. The at least one processor 416 can execute instructions, such as instructions stored in at least one memory device 418, to cause the head-mounted device 100 to perform any combination of methods, functions, and/or techniques described herein.

The head-mounted device 100 can include at least one memory device 418. The at least one memory device 418 can include a non-transitory computer-readable storage medium. The at least one memory device 418 can store data and instructions thereon that, when executed by at least one processor, such as the processor 416, are configured to cause the head-mounted device 100 to perform any combination of methods, functions, and/or techniques described herein. Accordingly, in any of the implementations described herein (even if not explicitly noted in connection with a particular implementation), software (e.g., processing modules, stored instructions) and/or hardware (e.g., processor, memory devices, etc.) associated with, or included in, the head-mounted device 100 can be configured to perform, alone, or in combination with the head-mounted device 100, any combination of methods, functions, and/or techniques described herein.

The at least one memory device 418 can include a library 420. The library 420 can include a gesture library with gestures associated with states of the head-mounted device 100. The gestures stored in the library 420 can be associated with states of the head-mounted device. The gesture interpreter 410 can map, and/or correlate, raw input data received from the head-mounted device with gestures stored in the library 420 to determine a gesture that the user 300 inputted into the wearable device.

In some examples, the library 420 can include multiple libraries. Each of the multiple libraries can be associated with a state of the head-mounted device 100. When interpreting a gesture, and/or determining a gesture that the user inputted into the wearable device 150, the gesture interpreter 410 can compare the input into the display 152 of the wearable device 150 to the gestures stored in the library in association with the state of the head-mounted device 100.

The head-mounted device 100 can include at least one input/output node 422. The at least one input/output node 422 may receive and/or send data, such as from and/or to, the head-mounted device 100 and the wearable device 150, and/or may receive input and provide output from and to a user. The input and output functions may be combined into a single node, or may be divided into separate input and output nodes. The input/output node 422 can include the front-facing camera 110, the gaze-tracking camera 114, the display 108, and/or any wired or wireless interfaces (such as Bluetooth or Institute for Electrical and Electronics Engineers 802.11) for communicating with the wearable device 150 and other electronic devices.

FIGS. 5A, 5B, and 5C show fields of view 112 captured by the front-facing camera 110. FIG. 5A shows the field of view 112 of the head-mounted device 100 without capturing the wearable device 150. In this example, in which the front-facing camera 110 did not capture an image of the wearable device 150, the head-mounted device 100 and/or the intent determiner 402 can determine that the user to 100 does not intend to provide input to the head-mounted device 100 via the wearable device 150.

FIG. 5B shows the field of view of the head-mounted device 100 capturing the wearable device 150. In some examples, the intent determiner 402 can determine that the user intends to provide input to the head-mounted device 100 via the wearable device 150 based on the wearable device 150 being within the field of view 112 of the front-facing camera 110. In some examples, the intent determiner 402 can determine that the user does not intend to provide input to the head-mounted device 100 via the wearable device 150 because the wearable device 150 is not disposed on a user's arm 160, and/or because the front-facing camera 110 did not capture an image of the user's arm 160, the wearable device 150 could simply be resting on a table.

FIG. 5C shows the field of view 112 of the head-mounted device 100 capturing the wearable device 150 on an arm 160 of a user 300. In this example, the intent determiner 402 can determine that the user intends to provide input to the head-mounted device 100 via the wearable device 150 based on the image recognizer 404 recognizing, and/or the front-facing camera 110 capturing the image of, the wearable device 150 disposed on the user's 300 arm 160.

FIG. 6 shows a data flow of a gesture inputted into the wearable device 150 and a resulting action performed by the head-mounted device 100. The user 300 can input a gesture into the display 152 of the wearable device 150 by, for example, sliding the user's 300 finger across the display 152. In the example shown in FIG. 6 , the user gestures the letter ‘C’ into the display 152. The wearable device 150 can send the raw touch input data to the head-mounted device 100. Upon receiving the raw touch input data, the head-mounted device 100 can perform trajectory buffering (602). Trajectory buffering (602) can include storing the raw touch input data. After performing trajectory buffering (602), the gesture interpreter 410 can pass the data through a convolutional network 604. The convolutional network 604 can include multiple nodes 606. In some examples, the number of nodes 606 can be the same as the number of letters, such as twenty-six. After passing the raw touch input data through the convolutional network 604 and nodes 606, the gesture interpreter 410 can perform a dictionary query (608). The dictionary query (608) can include comparing the interpreted gesture to a dictionary 610. The dictionary 610 can be an example of the library 420, with letters as examples of the stored gestures. In the example in which the head-mounted device 100 was in the home state, after performing the dictionary query (608), the head-mounted device 100 can launch the application (612).
